DANIEL NEWTON, OF DALTON, NEW HAMPSHIRE.

MACHINE FOR SAWING CLAPBOARDS.

Specification of Letters Patent No. 3,179, dated July 20, 1843.

To all whom I? may concern Be it known thatV I, DANIEL NEWTON, of Dalton, in the county of Coos and State of New Hampshire, have invented a new `and useful Improvement in the construction of a Clapboard Machine; and I do hereby declare that the following is a full and exact description of the same.

The improvement which I claim as my invention is for `sawing clapboards .from

plank, about 6 inches thick, and the ma` chine may be made of any dimensions to suit the owner; and it will not be necessary to describe the whole machine, but the parts which I claim; these are two; irst is the apparatus for setting the plank, or moving'- it forward toward the saw; this is done in t-he following manner viz. At each end of the carriage B near the side opposite the saw is attached one post, and on which hangs a shaft C I or 5 inches in diameter and at each end of this shaft on the inside of the posts, D, is a cast iron wheel E which mesh into gages F, which gages are fastened to the `headblock Gr, to which the plank is fastened for sawing. On the forward end of the shaft C, is a cast iron wheel H with one or more circles of holes in it, and a spring I on thev cross piece of the carriage with a knob on one end of it to fit in the holes of the wheel H. `At the forward end of the machine, and in a stationary manner is fastened a piece of cast iron jwvith a groove in it, which is cut oif on a slant. In this groove is a piece of iron or steel K with a pin through it to move on the slant and hung on a spring L at the other end. Ihen thecarriage runs back the iron K enters one of the holes and moving on the slant turns the wheel H to the next hole, when the spring I which was pressed out by K again enters the next hole, and holds it firm until the like operation is again produced, and thus the process for moving forward the plank is finished'. y i

My 2d improvement is the hanging of the arbor N for a circular saw M in such a position that one end of it can be raised or lowered alternately for sawing thick and thin edges of the clapboards, and the process of iron, andawheel with six armsT on the other end of the shaft. of wood V attached to the carriage which comes against one of the arms of'T every time the carriage runs back and turns the wheel one sixth of the way around thus raising and lowering the arbor alternately. Against the end of the arbor opposite to the saw is a fiat bar of iron X with a projection of steel on it about ith of an inch thick which when the arbor falls moves it in end toward the flank. In the sliding box O, S, is a projection the same as the former one which bears against a 3d projection o-n a piece astride the arbor, so that when the arbor rises these projections draw it back from the plank which is sawing the same distance it was moved toward the plank when it was lowered thus regulating the thickness of the clapboards. The process of moving the arbor in endis to avo-id making pne clapboard thicker than the other and thus the operation is complete.

What I claim as my invention and desire to secure by Letters Patent is- The hanging the, shaft of the saw so that one end of it can be raised or lowered in combination with the cam Q, and sliding box O, S for the purpose `and in the manner described. And I also claim the method `of regulating the set of the log on plank,

There is a piece
